Embodiment Construction

[0029]The present invention relates to a composite material and to a part made of composite material that uses braided strips of fiber tape imbedded in a thermoplastic matrix.

[0030]Turning now to FIG. 1, there is depicted a composite material 10 that is made of a plurality of fiber tape strips 12 that are braided together. The resulting composite material 10 has fibers oriented in to different directions. In FIG. 1 the fiber tapes strips are oriented in different degrees of configuration ranging from 20° to 80°.

[0031]FIG. 2, which depicts a cross-section view of one fiber tape strip 12, is concurrently referred to. Each fiber tape strip 12 is made of a single layer of unidirectional fibers 14 at least partially embedded in a thermoplastic matrix 16. All the conventional types of fibers may be used as the fiber 14, namely glass, carbon, aramid and other known or future fibers. Similarly, many different types of thermoplastic matrix may be used. However, for specific applications such...

Abstract

A composite material comprising a plurality of fiber tape strips woven or braided together. Each of the plurality of fiber tape strips is made of a single layer of unidirectional fibers. The fibers are at least partially embedded in a thermoplastic matrix. A tubular composite part is made from this composite material and of an internal film. A method of manufacturing the composite material comprises weaving or braiding the fiber tape strips, especially in the form of a tube. A method of manufacturing a composite part comprises pressurizing the film inside the tube while heating both the tube and the film up to their forming temperature so as to bond the film to the woven fiber tape strips.

Description

FIELD OF THE INVENTION[0001]The present invention generally relates to the field of composite materials. More specifically, the invention relates to a composite material, a composite part and methods for making such where the composite material is made of woven or braided fiber tape strips.BACKGROUND OF THE INVENTION[0002]Composite materials find an ever increasing place in the construction of aircrafts. Composite parts made from such materials have to meet stringent requirements, such as those related to fire, smoke and toxicity while being as light as possible while still being sufficiently stiff for their application. Moreover, it does not hurt if the part is as cheap as possible. Such is the case of air ventilation ducts used inside an aircraft.[0003]Typically, such parts are made of thermoset composite materials, which are quite labor intensive to manufacture, and consequently expensive. Furthermore, because these parts need to be made from many pieces of composite material ove...
